We all know the new turbo motors from M mean more tuning and the S63 4.4 liter twin turbo V8 is in several M models meaning it will be a popular platform. Thus far only AMS Performance has announced they are currently working on a turbo upgrade. Now Dinan enters the fray as well and offers some interesting insight into the platform as well as the modifications they have planned. These include bolt on modifications (tune,intake,exhaust) pushing 660+ crank horsepower as well as suspension upgrades. Then there is the built motor turbo upgrade coming.

BimmerBoost contacted Dinan and asked first regarding their bolt on stage upgrades. Dinan will offer a tune, intake, and exhaust putting the power somewhere in the 650 horsepower range. A dyno was asked for to corroborate the horsepower claims but Steve Dinan said as the products are not available yet no dyno or pricing information will be released.

Dinan: We are doing software, intake and exhaust which will make around 660hp. Then we are rebuilding the engine and putting larger turbochargers on it and it should produce around 750hp. We are also doing a coil over kit integrating the electronic shocks, along with tubular adjustable sway bars.

BimmerBoost:Do you have any dyno numbers to corroborate the intake, tune, and exhaust horsepower claims? Any pricing info as well?

Dinan: All the power numbers are targets for development. There are no completed products (production versions) to measure, so we do not have any dyno graphs. There isnít pricing available as of yet, since we don't have the completed products.

BimmerBoost: Why rebuild the motor for only 750 horsepower which the stock internals can handle?

Dinan: Different connecting rods and pistons for sure. They arenít strong enough to handle that power and the compression is too high for a lot of boost. Possibly a displacement change as well.

Expect 750 plus horsepower. There is no timetable for this and Dinan obviously has a lot of work ahead of them. Still, very exciting times ahead for the new twin turbo V8 motors. It will be interesting to see if any of this development carries over to the N63 V8 as well which would make it a tuning bargain especially if built motor N63's matched the S63's which are based on the same basic design.

Hmmmm. Thye need to build the motor to run 22 psi of boost and make 750 WHP with 1.4 more liters of displacement, than an N54 on stock internals? Not sure I am buying it 100%. Sounds like they are just erring on the safe safe safe side. Which is not always a bad thing, but just makes this type of upgrade very very expensive. Looking forward to updates.

Sounds about par with their other packages, always thought they were very pricey for so-so gains.

The only good thing about this is they are obviously playing the safe Dinan card... but I think a lot of people forget that Dinan takes over your BMW warranty. So you can have a tuned car with more power and everything is still covered like factory. As for the people going Dinan outside of their warranty.. that's a little foolish. All that money and no warranty. :/

Not quite to that extent, but it should have been built stronger from the factory and like someone else mentioned their power packages aren't that far off from this

Dinan is always super safe and the HP is just an estimate. A built motor with upgraded turbos is going to make some huge power.

Dinan is conservative and professional. They don't try to set some HP number goal or anything.

Plus the N54 comparison makes little sense as the S63tu has far more capability and will have far more torque under the curve. Peak HP to Peak HP doesn't tell teh whole story.

@Sticky either more power or less weight. Honestly the gap between this m5 and the last gen isn't as good as I thought it would be. F10 m5 0-60/ 60-130 times aren't that much better than the e60, top speeds are also about the same. The f10 just makes a crap load of torq and can launch hard as hell.

I would have wanted less weight. But BMW gave you plenty of power in stock form. It's a ton of power, the thing is just a pig.

What are the 60-130 times of both cars? I am curious how close they are now. I would have thought it would have been a pretty large difference, but thinking more on it - the S85 was geared more toward for this (pun intended).

Wow - you are right. The 80-120 km/h (all I could find) is dead even at 3.8s - the newer "M5" edges it out from 100-180 km/h @ 6.8s vs 6.9s
